I pulled the pan to install a silicon gasket while I am doing the motor mounts. Is there anything I should check/eyeball while the pan is off.

Also, the majority of the 375 bolts that held my oil pan on were only finger tight, is this right?

Edit - Rod bearings I have read. http://www.928oc.org/928oc_michigan/tbelt8.html

I started down that road when I had the pan off.
Doing the rod bearings seemed like a good idea, while you're in there and all that....until I started doing it. I started with the #6 bearing since I've read the #4 and #6 are the two that usually fail first but the one I replaced looked so good I stopped right there...

Working on jackstands laying on your back that job isn't so easy. If I had a lift I may have continued even though the bearings didn't show any significant sign of wear.

Just a thought.

I have used the cork oil pan gaskets and now use the silicon gasket. I have always just snuged up the oil pan bolts and do not torque them. I also dip the bolts in gasket sealer or have used hondabond/yamabond on the bolts. Last time I checked the bolts are still tight.
I believe going W/ the stud kit solves alot of this, but I am happy W/ using the bolts.
The other thing you might want to look at/replace is the rubber gasket for the oil pick up tube.

How many miles does your car have on it? Mine had around 80,000 and I agree with Craig, they really didn't need changing.

Brett Jenkins

95k miles.

My car had about 135k when I did the rod bearings. They were in very good shape, but I replaced them anyway. If I were to do it again, I wouldn't touch them until 200k miles.

The stud kit really helps with aligning the gasket. I recommend it highly.

What he said ^^^ Look, no hands!

jcorenman's picture gave me another idea....looks like it might be a little easier to install some headers while you have the underside dismantled

Did a little (SIYF) 'search is your friend' action and found this:

Nutshell is that buying one set of rod bearings may not be so easy due to three tolerance grades based on tightness. Buying aftermarket might not be as advisable either.

At least inspect the 2/6 rod journal and bearing. You may not replace it, but look it over. Also check the pickup tube/screen for gunk. Install a GTS baffle in the pan. Use yamabond on the pan bolts when you reinstall with a silicone gasket, or the stud kit from 928sRUS. Inspect the center webbing of the thrust journal for fore and aft play. It's prolly fine, but a good visual check just found one that was DITW, and the block had to be replaced. Look at the rear main seal for leaks.

If you do inspect 2/6 rod bearings be sure to replace the nuts W/ new ones. They are a one time use.

I have the oil pan off on my 155k GT.

I figure if I replace the rod bearings, I will always wonder if I did them right, presuming I don't have any obvious problems during the process. Lying on my back checking clearance does not sound like a simple task.

If I don't replace the rod bearings, I will always wonder If I should have.

So, if I have to wonder, I will do so and save myself the time and expense of changing them.

I haven't heard of failures on street cars, although I am sure it does happen.

Thanks for the post Andrew, you make me feel a little bit better about not touching them, although checking the 2/6 is still tempting...

As Ed Ruiz would say YMMV

My GT suffered a 2/6 rod bearing meltdown but it was on the track at the time under hard use. I agree that street use cars won't suffer. As for checking the clearance, you can use Plastigauge. I've used it before and it's pretty accurate. If the pan is off, I'd sure check it, doesn't take much time or money.
